A grade g1=+2.00% intersects grade g2=−1.40% at a vertex whose station and elevation are 78+60 and 7855.35 ft, respectively. An equal-tangent parabolic curve 505 ft long has been selected to join the two tangents. Compute station elevations for the curve, for stakeout at full stations.

A sag vertical curve is to join a grade of g1=−3.50% to a grade of g2=−1.25%. What is the minimum length of the curve for acceptable passing sight distance at night, with headlight illumination? Express your answer in feet to five significant figures. there is no more info. this is all that was given to us.

A -3.4% grade intersects a 4.2% grade at STA 5+180 at an elevation of 125.98. A vertical curve of length 120m is to be run forward from the point of intersection, and a curve of length 80m is to be extended back forming an unsymmetrical curve. a.)Determine the elevation of the lowest point. b.)Determine the elevation of the second quarter point on the curve.

A descending grade of 4.2% intersects an ascending grade of 3% at sta. 12+325 at elevation 14.2 m. These two grades are to be connected by a 260 m vertical parabolic curve. A reinforced concrete culvert pipe is to be constructed with its top 30 cm below the subgrade (or the lowest point of the curve) What will be the invert elevation of the culvert?

A negative 5% grade meets a positive 3% grade at vertex elevation 146.24m directly under an overpass bridge whose underside is at elevation 152.74 and carries another road across the grades at right angles.What is the longest parabolic curve that can be used to connect the two grades and at the same time provide at least 5 meter clearance under the bridge at its center line? If the underside of the bridge is level and is 12 meter wide, Find...

A 0% grade meets a 3% grade at station 24+00.00 and an elevation of 372.15 ft. For a passing sight distance of 2,000 ft, find the following: a. Minimum length of the vertical curve that allows for passing using the minimum curve length equations. b. Calculate the elevation of the middle point of the curve. c. Calculate the elevation of the road at station 23+00.00.
